Network densification via deploying dense small cells is one of the dominant evolutions to increase network capacity towards future cellular networks. However, the complex and random interference in the resultant interference-limited heterogeneous cellular networks (HCN) may deteriorate packet transmission reliability and increase transmission delay, which are essential performance metrics for system design in HCN. By modeling the locations of base stations (BSs) as superimposed of independent Poisson point process, we propose an analytical framework to investigate delay and reliability tradeoffs in HCN in terms of timely throughput and local delay. In the analyses, we take the BS activity and temporal correlation of transmissions into consideration, both having significant effects on the performances. The effects of mobility, BS density, and association bias factor are evaluated through numerical results.

“…(Refer to [17]- [20] as a sample of some recent results.) In this paper, we extend the analysis of uplink tow-tier networks presented in [15] to the case in which each FAP has a backhaul constraint that limits the number of users it can service. We derive analytical upper and lower bounds on the outage probabilities experienced by the users serviced by the FAPs.…”

“…We consider the open access scenario with access parameter κ ∈ [0, 1], studied in [2] for downlink communications and in [15] for uplink transmission, when the FAPs have no backhaul constraints. Let d(u m , a) denote the Euclidean distance between the (femto or macro) access point a and u m .…”

Multi-tier cellular communication networks constitute a promising approach to expand the coverage of cellular networks and enable them to offer higher data rates. In this paper, an uplink two-tier communication network is studied, in which macro users, femto users and femto access points are geometrically located inside the coverage area of a macro base station according to Poisson point processes. Each femtocell is assumed to have a fixed backhaul constraint that puts a limit on the maximum number of femto and macro users it can service. Under this backhaul constraint, the network adopts a special open access policy, in which each macro user is either assigned to its closest femto access point or to the macro base station, depending on the ratio between its distances from those two. Under this model, upper and lower bounds on the outage probabilities experienced by users serviced by femto access points are derived as functions of the distance between the macro base station and the femto access point serving them. Similarly, upper and lower bounds on the outage probabilities of the users serviced by the macro base station are obtained. The bounds in both cases are confirmed via simulation results.

Employing multi-tier networks is among the most promising approaches to address the rapid growth of the data demand in cellular networks. In this paper, we study a two-tier uplink cellular network consisting of femtocells and a macrocell. Femto base stations, and femto and macro users are assumed to be spatially deployed based on independent Poisson point processes. Under open-access policy, we derive analytical upper and lower bounds on the outage probabilities of femto users and macro users that are subject to fading and path loss. We also study the effect of the distance from the macro base station on the outage probability experienced by the users. In all cases, our simulation results comply with our analytical bounds.
